INTAKE PORT PROBING WITH FLOW BALLS

Post by HIGHOCTAIN2000 »

WHEN YOU PROB AN INTAKE PORT WITH FLOW BALLS I UNDER STAND THAT WHEN FLOW IS REDUCED IT IS A BUSY AREA, I UNDER STAND THAT WHEN TRERE IS AN AREA WITH NO CHANGE IT IS A DEAD AREA, WHAT DOES IT MEAN WHEN YOU PROB AN AREA AND YOU GAIN FLOW.

The flow is reattaching after the ball. Which wasn`t before , caused by shape/too high velocity or both.

When probing the air flow in a port I think it's best done with a pitot tube. Not even sure what flowz balls are?

Probing with the proper Pitot tube puts you light years ahead of finding out where the air mas is moving thru a port then flow balling a port if you want my 2 cents worth!

Flowballs really help if teamed up with Pitot airspeeds.

If yòu in a real serious development session on a head and you have one you can sacrifice for the cause then cutting it up and drilling it with long bits to press or glue in 3/32" tubes around the valve bowl and taking pressure readings off of each tube at .050" valve lift intervals will provide a very clear picture of where the air mass is going a this in turn will provide you with insite as to how well your port shape is making use of your valve bowl Throat and valve size.
You want to use thick wall tubing like Aluminum so you can round over the tubing nose that sticks out into the valve bowl wall.

This fully beats out flow Ball useage and if you tie it in with Pitot tube readings in the runner is very informative to say the least!

Blowing thru the intake manifold side of the port, having the cylinder bore adapter attached to head, is a very good alternative to do this.
Helps whatever the region of valve you want to check, as well as it´s a prototype head or not.

I love my pitot tube, but the flow balls are 1a to me.

It means they both are #1 to me. The flow balls are 1a and the pitot 1b if I had to rank them.

All a flow bench is for is the lifeblood for visual aides.

Yes I agree. How do you utilise them, what are you looking for and how do you interpret it? I read somewhere a long time ago that they can be used to re-attach the flow?

I find an S-type velocity probe works best for me.
With a velocity probe, you can find spots that may be flowing backwards, or eddies.
